Sandbox Gatekeeper - Screener Version

Sandbox Gatekeeper - Screener Version
This indicator scans for stocks exhibiting volatility compression before potential breakout entries. It combines multiple technical filters to identify candidates that meet specific structural criteria.
Key Features:
- ATR Volatility Compression: Identifies stocks with historically low volatility (bottom 20% of their 60-day ATR range)
- Base Structure Analysis: Evaluates consolidation tightness over a 20-day lookback period
- Volume Confirmation: Tracks relative volume (RVOL) to confirm institutional interest
- Trend Alignment: Requires golden cross configuration (EMA 50 > EMA 200) and uptrend confirmation
- Market Context: Checks SPY trend as macro risk tape
- RSI Filter: Excludes overbought conditions (RSI > 75)
How to Use:
1. Add this indicator to the TradingView Stock Screener as a custom filter
2. Set the filter condition to "equals true"
3. The screener will display only stocks that pass all Gatekeeper criteria
4. Use the results as a starting point for further chart analysis
Note: This is a screening tool, not a trading signal. Always perform additional analysis before entering trades.
